NFL Matchup (Saturday):

Jaworski shows how the 49ers use an unconventional formation to dictate a favorable matchup that repeatedly leads to wide receiver Michael Crabtree vs. a linebacker

Hoge describes a blitz scheme using second- and third-level defenders that the Broncos used to pressure Ravens quarterback Joe Flacco in their week 15 game.

In week 15, the Ravens’ run game was most successful in single-back, Jaworski explains why and how.

Disregard the 49ers at Packers week one game, contends Hoge, explaining how Packers quarterback Aaron Rodgers has become more successful late in the season by using his legs to avoid pressure.

Though the 49ers appear to be a pass-heavy team since the change to quarterback Colin Kaepernick, they are still a run-first offense. Hoge uses the “Coaches Clicker” to show why.

Jaworski shows how the 49ers disguised blitzes in week one to produce three sacks of quarterback Aaron Rodgers.

NFL Matchup (Sunday):

Quarterback Russell Wilson has impressed critics with his ability to make plays with his legs. Jaworski shows a 49 yard-completion that exemplifies the Seattle Seahawks signal-caller’s ability to make throws on the run.

Arguing that the Seahawks’ and Carolina Panthers’ offenses are similar, Hoge analyzes key plays in the Panthers offense that led to 394 rushing yards in their two meetings with the Falcons this season.

Jaworski, using the telestrator, shows how the New England Patriots run-action to draw the safeties down opened up lanes for an easy touchdown throw to wide receiver Brandon Lloyd in their last meeting vs. the Texans

Jaworski explains how the Falcons’ motion and unconventional alignments can mollify the Seahawks’ potent press coverage.

Falcons’ tight end Tony Gonzalez has the most third-down catches this year and Hoge shows how he wins against man or zone coverage.

JJ Watt and the Texans defense must get pressure on Tom Brady to contain the Patriots pass attack, and Hoge pulls out the “Coaches Clicker” to explain a successful zone-blitz the Texans used in their last meeting.

The Patriots defense held running back Arian Foster to 46 yards in Week 14 playing in multiple defensive fronts. Hoge shows how the Patriots’ key is sustained penetration.

Jaworski analyzes Matt Schaub’s interception in the Texans first meeting with the Patriots, showing how the quarterback needs to manipulate the safety before making deep throws downfield.

Jaworski shows Vince Wilfork’s dominance against the run in the Texans at Patriots week 14 game.
